Towards operational AI regional forecasting: extreme-event skill and near real-time verification with HRRRCast
Webinar Date : October 8, 2026 Improving convective-scale skill in regional AI weather models requires better representing rare high-impact events, broadening variable output, training at native resolution and demonstrating performance in real-time settings. Here, we evaluate these challenges using HRRRCast, a data-driven convection-allowing emulator trained on the High-Resolution Rapid Refresh (HRRR) analyses data. HRRRCast combines […]
The Community Radiative Transfer Model in the UFS: Connecting Model Physics to Satellite Observations
The Joint Center for Satellite Data Assimilation develops the Community Radiative Transfer Model (CRTM) in partnership with NOAA NESDIS/STAR, the Environmental Modeling Center, NASA, the U.S. Navy and the Air Force. The CRTM serves as the observation operator within the JEDI/UFO framework used for NOAA’s global and regional data assimilation, and it is also the […]

NWS launches Warn-on-Forecast System Demonstration Project
When National Weather Service (NWS) forecasters wrestle with decisions about convective warnings, the pivotal moment often comes when radar and/or satellite imagery indicate that a threat, e.g. a tornado, large hail, strong winds, is imminent or already occurring. Prior to that moment, the available data may not instill enough confidence for the forecaster to pull […]
